over the last couple of days, this oscar in my tank has started to act funny. it is always first to the side of the tank to beg for food and doesn't seem to know when he is full. it is always looking for food in the tank and never even considers hiding or swimming away. now all it does is hide and doesn't have its usual hunger. when it does decide to come out it just kinda floats and looks unwell. i attributed some of the hiding and scardeyness to the new addition of a stingray as it is a bit bigger than it and its his place in the hierarchy has changed but then today its fins are clamped and it has this massive white bit of poo hanging out of him which looks seriously unhealthy..... can anyone help me out here???
